Backing up file systems means copying file systems to removable media, such as tape, to safeguard against loss, damage, or corruption. Restoring file systems means copying reasonably current backup files from removable media to a working directory.
This chapter describes the ufsdump and ufsrestore commands for backing up and restoring UFS file systems. Other commands are available for copying files and file systems for the purpose of sharing or transporting files. The following table provides pointers to all commands that copy individual files and file systems to other media.
